Alex and I reported last week that Michele Bachmann's camp had started making inquiries about TV air time to start after the July 4 holiday weekend, and Bachmann sources tell me her buy in Iowa begins tomorrow.

The Iowa airwaves, as Ben noted earlier, have gotten cluttered. A small chunk of Bachmann's purchased time includes slots around the Sunday talk shows, which will include an appearance by Tim Pawlenty.

UPDATE: It's unclear if the buy is cable or broadcast, although one source familiar with the Iowa airwaves said nothing appears to have been purchased for broadcast so far. But the Bachmann source said it's a statewide buy that begins with a bio, self-defining spot about the candidate, and called it a "significant" buy.
